I am very excited that bigergm is available on CRAN. cran.r-project.org/web/packages/b… It is an R package born from a great collaboration with Juan Nelson Martinez Dahbura, Shota Komatsu, Takanori Nishida at Sansan, Inc, Cornelius Fritz and Michael Schweinberger at Penn State University.

Modern supply chains don't look like trade theory 101! They involve constant border crossings, each now hit by tariffs. Tariffs raise prices, but the more important thing they do is disrupt supply relationships. 1/ graphic h/t @scottlincicome .

This risk is highly skewed with the most systemic repository affecting almost 90% of all repositories only two steps away. Protecting only the ten most important repositories reduces vulnerability contagion by nearly 40%. dl.acm.org/doi/10.1145/36…

This version of the paper analyzes 35, 473 repositories with  696, 790 software dependencies of the Rust's ecosystem of libraries. We estimate a structural model of network formation and use it to guide an analysis of the systemic risk embedded in the dependencies.

Today, between the islands of Tavolara and Molara, I came across Koru, Jeff Bezos' beautiful sailing yacht.

My first time at the @TheOfficialACM Conference on Economics and Computation (EC24). I learned a lot on LLMs and AI. Today my coauthor Co-Pierre Georg will present our paper on software dependency networks. All in all a good experience, and hope to come back next year.

@lihua_lei_stat SBMs are special cases of ERGMs, and you can interpret ERGMs as stationary equilibrium of a potential game with stochastic best response. Need a few assumptions, but it works in both directed and undirected case. Happy to chat at Cowles tomorrow.

#econtwitter Is there a game theoretic foundation for stochastic block models?

I did the same on my very first day with my brother @angelo_mele. We actually said, clearly nobody is using this door while the lateral ones are overcrowded, let's be smart! We did both OK for those worried

@johnjhorton At Bocconi they say if you walk in between the lions at the entrance you won't graduate. I walked in between them on the first day because I assumed they would be on the outsidelike the teatro massimo in Palermo, instead of inside, which makes zero sense

I hope all the social network folks are excited about the International Sunbelt Social Networks conference in Edinburgh, Scotland in less than a month! Have you ever tried to analyze large networks with thousands, tens of thousands, or hundreds of thousands of actors?

@albertobisin @ben_golub When I was taught the theorem in Italy , that’s how they called it, Dini’s theorem. Then it took me a few minutes to figure out it was the same theorem when they called it implicit function theorem here. Also my English was pretty bad at the time, so maybe that was it…

@ben_golub I would like to add a motion to stop referring to the "Implicit function theorem" and start calling it with its rightful name of "Dini's theorem"!

We have already succesfully used the package in our research and have been able to estimate ERGMs models with community structure with more than 250,000 nodes. You can find some of this work in my webpage. meleangelo.github.io/research.html
